You can put this solution on YOUR website! a nonstop train leaves new york for los angeles traveling at a constant rate of
80 miles per hour.
another nonstop train leaves los angeles for new york, at a constant rate of 60
miles per hour both traveling on the same straight track.
how far apart are the fronts of the trains in miles 1 hour before they meet?
:
We can use relative speed here, trains going towards each other, their speeds
are additive, 80 + 60 = 140 mph
:
All we have to ask ourselves is how far will be traveled at this speed in 1 hr
Obviously 140 miles apart, one hour before they meet
